A mechanical assembly consists of a rod with a bearing on each end. The three parts are manufactured independently, and all vary a bit from part to part. The length of the rod has mean 11 centimeters (cm) and standard deviation 0.13 millimeters (mm). The length of a bearing has mean 2 cm and standard deviation 0.03 mm. What are the mean and standard deviation of the total length of the assembly? (Round your standard deviation answer to four decimal places.)

μ = __________cm

σ = ___________ mm
